Are things getting stale with your AR-15? We all know that variety is the key to stimulation, so what can you do to spice things up?

Explore a new shooting niche with this sturdy cartridge. 

Why should you choose the 300 BLK for your AR-15?

  • Lower powder charge saves barrel life
  • Appropriate for many state hunting regulations
  • Ideal for using with a suppressor
  • Subsonic without a suppressor

As you can see, it’s a specialty cartridge that shines at short-range shots or in a suppressed AR-15.

A Quick Guide to Distance: How Far Will Your Bullet Go?

For an AR-15 chambered in 300 BLK keep these rough measurements in mind:

  • Long Range: 300 yards and above
  • Medium Range: 150 – 300 yards
  • Close Range: Up to 150 yards

Although it’s not the most powerful cartridge, it still remains the most quiet and effective at close range. Then again, who says it’s not capable of going farther? Our favorite thing about this cartridge is how versatile it can be.

So what about you?

Are you ready to step up to longer distances or just improve your short shot? A scope will be beneficial for both.

What Magnification Do You Need?

Although it’s growing in popularity, working with this cartidge can mean a slight learning curve. That’s where a 300 blackout scope comes in to save the day!

However, there isn’t one scope to fit every person. Your typical trip in the field will determine what kind of scope you need.

  • Long Range (300 yards and above)
  • At this range, you likely won’t be taking down much game due to the modest penetration of this caliber. However, you can still show off at the range and leave your crew speechless. If this sounds like you, you’ll want at least 9x magnification or higher.

  • Medium Range (150 – 300 yards)
  • At this range, the coyotes and foxes will be wishing they’d found other property to trespass. If you want to clear your land of varmints, you’ll use about 5 – 9x magnifications.
  • Close Range (Up to 150 yards)
  • Here, you can definitely hunt small game or hit a bullseye dead-on. Since this is the range where this caliber naturally excels, using 1 – 4x magnifications gives you a huge boost.

Let’s see what kind of scopes give you an advantage over the competition!

Which one of these will raise the bar on your next outing?

1. Nikon P-300 BDC 2-7x32mm Riflescope

Nikon P-300 BDC SuperSub Reticle Riflescope, Black, 2-7x32

Check Price on Amazon

Are you a fan of Nikon’s M and P series? If you said “yes” and you have some 300 Blackout rounds waiting for action, this is your ideal match. Unless, of course, you’re primarily shooting long-range targets.

After you get your aim right where you want it, you can lock your turrets and snap back with every shot. It’s just a matter of lifting and releasing to find your zero again.

Pair this with a fantastic 98% light transmission and you’ll always see clear ahead. It’s calibrated for the 300 Blackout cartridge to shoot out to 600 yards. Every 100 yard increment uses an open circle point with a hash mark between each one.

As a matter of fact, this isn’t the only feature specific to 300 Blackout cartridges.

Nikon SuperSub BDC Reticle

At first, it may look like any other BDC reticle, but there’s a surprise. Nikon made this BDC specifically for supersonic and subsonic ammunition like the 300 Blackout. Since their ballistics specs are so unique, why wouldn’t you want a unique BDC to match them?

Otherwise, every shot leaves too much room for doubt.

The Bottom Line

Weighing in at only a pound and measuring less than one foot, you can’t deny this scope is easy to handle. If your aim stays within a medium range or lower, this 300 Blackout specific scope is a dream. Locking turrets, nearly perfect light transmission, and a specialized reticle all at a low price can’t be beaten.

2. UTG 3-12X44 30mm Compact Scope

UTG has a fantastic catch for anyone who never knows what to expect in the field. If you need short range one minute and quickly scale up to long range, you can do that ¼ MOA at a time.

No matter how far you’re aiming, you’ll never have to worry about parallax. From 10 yards to infinity, your crosshairs will always hold steady. However, using the side wheel adjustable turret (SWAT) that accomplishes this is a small inconvenience since it’s a little tight.

Otherwise, the only other complaint is the hefty 2 pounds this scope adds to your rifle. Some prefer it, others don’t, but either way it takes some practice to adjust.

Now that we have the bad news out of the way, let’s talk about the highlights!

Zero locking turrets save you time and frustration in the field. That means once you zero in, you’re set. Simply zero in and lock it, then on your next shot all it takes is a tap and you’re back in action!

Believe it or not, the target turrets aren’t the only feature that locks and resets in a flash.

Illumination Enhancing (IE) Reticle

Although IE reticles aren’t for everyone, they’re often the light of many rifle owners’ eyes – literally.

Even better? With this scope, you get 36 different color options to complement the high-quality emerald lens. Switch through them effortlessly with the tap of a button. Then when you find one you like, lock it in and snap back to it in an instant!

The IE feature does make this scope slightly heavier, but it’s well worth the “enlightening” experience!

The Bottom Line

If you want big benefits from a small package, look to UTG. Even though it’s under a foot long, this scope lets you cover a broad distance in any light setting. Best of all, it doesn’t waste any time since its best features lock and reset in a snap. Will it be your rifle’s next companion?

3. Vortex Optics Diamondback HP 4-16×42 SFP Riflescope

Vortex Optics Diamondback HP 4-16x42 Second Focal Plane Riflescope - Dead-Hold BDC Reticle (MOA)

Check Price on Amazon

Durable, resilient, simple. Vortex gives you everything you need in one scope without piling on flashy features. It’s not made to do all the work for you, just to shine at what it’s made to do.  

With an aircraft grade aluminum build, it resists heavy recoil and all but the most extreme environments. It’s also loaded with argon gas to prevent water leakage and foggy lenses, plus an accessory lens cap to protect it on the road.

However, none of these things weigh it down while it maintains a lightweight under one pound.

You won’t find another long range gun of this quality, at this price, with such straightforward use. Actually, the only complaint we can find is that the parallax is unreliable past 50 yards.

However, such an elite optics brand wouldn’t allow a slight downfall without offering a way around it!

The Dead-Hold Reticle

This infamous BDC reticle is an original Vortex creation. It uses a format you’re familiar with and doesn’t leave any room for last-minute doubts. Reducing hold-over corrections and windage guesswork gives you the confidence for a deadly accurate shot.

Then in those moments, you aren’t 100% sure, the windage and elevation pop-up dials help you fine-tune. Audible clicks let you know exactly what you’re doing without taking your eyes off the prize.

The Bottom Line

Whether you’re a beginner or just a little rowdy in the field, this scope will be your best friend. Crush targets at close range or test your 300 Blackout round on that 1000 yard shot.

Best of all, you can do it without any learning curve or complications. You get all the necessities without sacrificing integrity or adding weight to your pack. Get out there today and see how easy it is to step up your game with Vortex. Would also be a nice M4 optic.

4. Nikon M-223 3-12x42mm Riflescope, SF MatteNikon M-223 3-12x42mm Riflescope, SF Matte, Nikoplex Reticle

Check Price on Amazon

Want another option to combine with your .300 blackout AR-15? Try this optic from Nikon, which comes with magnification powers between 3x and 12x: perfect for taking advantage of the relatively close to mid-ranges dominated by the .330 blackout’s power and stealth.

This riflescope has an additional thing going for it in the form of a 42 mm objective lens. This is actually a good thing for relatively close-range optics like this one since it means the scope will provide a clear sight picture, even in lowlight environments. Multicoated optics also work to ensure this happens each time you sight-in to your target.

But that’s not all. The riflescope features a quick focus eyepiece that is easy to get used to and take advantage of, especially when you’re tracking close quarters targets or opponents in tactical environments. Interestingly, the scope comes with a parallax adjustment turret that you can take advantage of to offset that value for the longer ranges available.

Turrets and Unique Reticle

You’ll more commonly benefit from the spring-loaded and zero-reset windage and elevation adjustment turrets. These will help you to compensate for those variables at any distance. Even cooler is the rapid action turret technology that lets you position the proprietary “Nikoplex” reticle right on your target at any distance up to 600 yards.

For stealth operations or hunts, this can be very useful and even a lifesaver. It’s a unique benefit you can’t find anywhere else and it’s just one of the reasons why this riflescope could very well be worth your time.

The Bottom Line

This scope is quite decent through and through and is fairly affordable to match. We’d recommend it if you want something suitable for tactical or close to mid-range engagements or that’ll go well with your stealth AR-15’s build and overall accessories.

Your next best 300 Blackout scope is just one click away and ready for action. Are you?
